According to the Nature report, the group of physicists from the European Space Agency’s Planck satellite announced by the investigation and found that the big bang gravitational waves very early indeed a mistake, an official report will be published next week.

EarthSky website reported that for the first time astronomers have captured an intense flash of radio waves, known as rapid real-time radio outbreak. The incident lasted only a few milliseconds, but some scientists argue that the outbreak may be derived from 5.5 billion light years away, indicating that the signal is caused by a huge source of energy produced.

Low mass stars (aka cold stars) volume is generally equal or smaller size of the sun, the stars in the universe’s most common species, but their age is difficult to determine, because it can be observed properties to hardly make a difference over time .
